Neat Fact of the Day: Given an NTLM hash, the video card in my PC can attempt 1.5 - 2 Billion password attempts per second to crack that hash with brute-force, versus 9 million passwords per second with my CPU.
Video Card: Nvidia GTX 560 Ti (384 cores) using ighashgpu.
CPU: Intel i5 2500k @ 3.5GHz (4 cores)
Lesson learned: CUDA is freaking awesome. I can crack the NTLM hash of a 10-character password consisting only of digits in under five seconds.
